However, the guidelines of TNFa withdrawal when disease remission is achieved remains unclear. Objective. To study the efficacy and safety of different TNFi withdrawal regimens in patients with juvenile idiopathic arthritis without systemic manifestations due to the achievement of long-term disease remission. Patients and methods: The prospective simple randomized trial included 76 patients with JIA without non-systemic juvenile idiopathic arthritis, with a disease remission duration of ≥24 months, developed under the conditions of treatment with TNFi. Of these, 38.2% are male, the average age is 11.6 years; 67 (88.2%) patients received etanercept (0.8 mg / kg / week. subcutaneously 1 time per week), the rest – adalimumab (24 mg/m2 subcutaneously 1 time in 2 weeks). Depending on the withdrawal regimen, patients were divided into three groups: in the I group, one-time withdrawa was presented, in the II group, the interval between administrations was of two times and the III group was reduced by a dose of two times. The main indicator of the study: preservation of the stage of inactive disease / remission (according to the criteria for remission of C. Wallace) for 6, 12 and 18 months after the withdrawal of TNFi. Results. At the time of withdrawal of TNFi, the average duration of the disease was 7.3 years, the duration of therapy with TNFa was 5 years, remission – was 4.4 years. For 6, 12 and 18 months after the withdrawal of TNFi, the stage of remission persisted in 44 (57.9%), 21 (27.6%) and 18 (23.7%) patients. Exacerbation of disease was registered in 58/76 (76%) patients. Biologic therapy was resumed in 56/58 children, in all cases the stage of inactive disease was reached. Among patients with exacerbation of JIA, 23/56 (41%) continued to receive disease-modifying antirheumatic drugs. Predictors of successful withdrawal of TNFa in patients with non-systemic JIA 6 and 12 months after discontinuation of the biological therapy were the female sex, the absence of HLA B27, antinuclear factor and long-term methotrexate therapy; predictors of exacerbation - increasing in the serum concentration of calprotectin (S-100 protein), the presence of subclinical synovitis according to ultrasound and MRI of the joints and uveitis. Conclusion. After the withdrawal of TNFi, the remission stage for 6 and 12 months persisted more than in half and one third of patients. The withdrawal regimens did not affect the duration of the remission of disease. The resumption of biological therapy in the exacerbation stage of JIA made it possible to reach the remission stage in most patients.

The balance of the mycobiome affects the stability of the microbiome, while the interaction between gut bacteria and fungi can be both beneficial and detrimental to the latter. The interaction between the mycobiome and the host is achieved through modulating the immune system and affecting the metabolism, which, in turn, can modulate the outcome of the disease. Fungal gut dysbiosis, for which we propose the term “dysmycobiosis”, is closely related not only to gastrointestinal disorders (such as inflammatory bowel diseases, irritable bowel syndrome, celiac disease, colorectal cancer, and pancreatic ductal adenocarcinoma), but also to various extraintestinal pathologies, including chronic liver disease, metabolic disorders, and neurological disorders. The investigation of the mechanisms underlying gut dysmycobiosis will promote the development of novel diagnostic and therapeutic targets for inflammatory and other human diseases.

A register is a critical component of the healthcare system. It consists of the informational part (number of patients, spectrum and severity of pathology, dynamics of each patient's condition, administration of specific drugs, and therapeutic effects) and an analytical part (treatment efficacy, planning individual and regional needs for specific drugs and therapeutic effects, development and evaluation of management protocols, etc.). In Russia, despite the existence of the National Federal Register, the number of parameters collected is limited; the Register lacks information about the disease course, clinical characteristics of patients, outcomes, and treatment costs. Thus, the existing shortcomings of the Federal Registry do not allow us to address the problems related to the management of the healthcare quality for patients with systemic juvenile idiopathic arthritis (sJIA). Objective. To analyze geographical, demographic, and clinical characteristics of sJIA patients receiving biologicals, time to diagnosis, and time to admission to a Federal Center according to the Federal Register of the Russian Federation. Patients and methods. We conducted a retrospective study that included 927 sJIA patients receiving biologicals according to the Federal Register. Results. The majority of patients resided in the Central and Volga Federal Districts (221 (23.8%) and 206 (22.3%), respectively). Half of the patients (n = 472 (50.8%)) had their disease onset before the age of 5 years. The following symptoms were registered at disease onset: fever (n = 908 (98%)), rash (n = 748 (80.7%)), enlarged liver and/or spleen (n = 562 (60.6%)), and serositis (n = 198 (21.4%)). A total of 708 children (76.4%) had active arthritis at the moment of disease onset, whereas 130 patients developed arthritis later. Median time to the development of articular syndrome was 24 months. Median time between the disease onset and the diagnosis was 2.93 months. Median time between the first symptoms and admission to a Federal Center was 6.7 months. Conclusion. Analysis of data from the Federal Register of sJIA patients receiving biologicals demonstrated that sJIA in the Russian population is characterized by an acute and early onset with severe extra-articular manifestations, and articular syndrome. The diagnosis was usually verified and the patients were hospitalized to specialized rheumatology departments of Federal Centers within 5 months.

AIIs are characterized by high incidence and can result in severe or even life-threatening dehydration. Therefore, rehydration is the first and compulsory component of the treatment in these patients. In addition to oral rehydration, probiotics are crucial for AII treatment. Probiotics are live microorganisms that can improve the health of the host when prescribed in adequate doses. Multiple microorganisms with probiotic activity have been isolated so far. Saccharomyces boulardii, a probiotic yeast, has a special place among all probiotics. One of its strains, S. boulardii CNCM I-745, has demonstrated its high probiotic activity and safety in numerous randomized clinical trials and confirmed by meta-analyses. In particular, in a randomized controlled trial SABINA conducted in Argentina, S. boulardii CNCM I-745 showed higher efficacy than Bacillus clausii in reducing the duration of acute diarrhea in children. In 2023, the European Society for Pediatric Gastroenterology, Hepatology and Nutrition (ESPGHAN) provided updated recommendations for the use of probiotics for the management of AIIs. Among other things, it states that S. boulardii CNCM I-745 can be recommended for the management of acute gastroenteritis in children, since there is evidence of reduced duration of diarrhea. Thus, isolation of S. boulardii CNCM I-745 provided new treatment options for a wide range of diseases, including AIIs.

To assess the species composition and correlation of microflora from the various parts of the upper and lower respiratory tract in children with cystic fibrosis. Patients and methods. 94 patients aged 2 to 18 years diagnosed with chronic rhinosinusitis with cystic fibrosis which had surgical intervention were included. The species composition of microflora was obtained from paranasal sinuses and nasal cavity, evaluated intraoperatively, from trachea during intubation in comparison with the actual (1-3 weeks before the intervention ) results of bacteriological test of induced sputum and / or material from the posterior pharyngeal wall, as well as the most \"clinically significant\" microflora in the anamnesis.
